What is hereditary hemorrhagic telangiectasia?

Also known as: HHT, Osler-Weber-Rendu syndrome, Osler-Weber-Rendu disease.

Hereditary hemorrhagic telangiectasia is a disease in which some blood vessels develop abnormally into telangiectasia (enlarged small blood vessels in the skin) and/or where some little arteries drain directly into veins (instead of going first into capillaries) called arteriovenous malformations. Both of these can result in the blood vessels bursting and bleeding.
